Thanks, Axel. I did make a storyboard which I synched to the song to get an animatic and build the idea tightly around the song. That way I also knew the timings I needed for each shot and added or removed as was necessary. I then printed that storyboard and wrote annotations on each shot by hand. That was my guide on the whole shoot, and it was a bless. The rest was in my head.
I will upload a three way comparison (storyboard/raw footage/final image) to my Vimeo account in the next few days. I will also upload the the music video in (hopefully) higher quality (I reckon Vimeo's compression holds grain better than YouTube). There'll be a 12Mbps video to download as well.
Yeah, I bought these Minolta lenses because they were cheap, back when I bought the GH2 and they were used. I've become very fond of them. I only wish the wide open performance of the 28mm was better, but I still like the organic feel they bring to the table. I want no digital lenses today!
